| abstract |
A method of producing hydrocarbons and optionally halite from a subterranean oil shale formation containing zone(s) of halite, by penetrating said formation with at least one borehole and leaching or dissolving the halite from the formation with a solvent fluid so as to form a cavern(s) and/or interconnected cavities, followed by fracturization and/or rubblization of the oil shale surrounding the caverns or cavities, and thereafter injecting into the fracturized and/or rubblized zones, a pyrolyzing fluid to effect insitu hydrocarbon recovery therefrom. |
